CONVEYER.

Application filed November `5, 192). Serial Noyfllfl-l.

To all lwhom t may concern Be it known that Max ELLRIGH, citizen of theGerman Republic, residing at 173 New York Avenue, Jersey City, in thecounty of Hudson and State of New Jersey, has invented ce-rtain new and`useful lmprovements in Conveyers, Aof which the folylowing' is aspecification. l

The present invention relates to conveyers for conveying tubularlcontainers, particularly such which are used to convey tubes containingcork composition for treatment in an oven. y

My invention has for its object to provide means which willautomatically and securely grip or connect the tubes to the conveyer andautomatically release the same'` after they pass out from the oven orapparatus in which they are treated.

With the? object in view my invention con sists in the novelconstruction, arrangement, and combination of parts as will behereinafter more fully described and defined in the appended claims.`

In the accompanying drawings in which similar reference charactersdenote correspondingparts, Fig. l isa top plan view of one end and ofone side of a tube conveyer; Fig. 2 is a vertical sectionon line 2,-2 ofFig. 1; Fig. 3 isa section on line 3 3 of Fig. 2; Fig. et is a more orless diagrammatic view of one end of theconveyer; Fig. 5is an elevationof a detail, and Fig; 6 isa section on line 6-6 of Fig. 1.

Referring specifically to the drawing 10 denotes oneof the sprocketwheels arranged on shaft 11 and over which run two parallel endlesschains 12, of which only one is shown in the drawing. These chains areadapted to be connected together by frames 13 for supporting the tubes15 containing the material to be treated in an oven, while conveyedthrough the latter. Each chain consists of rollers a, mounted on pins Z)and lconnected by end links c and d. The frames 13 are each composed ofa pair of parallel bars 13, 13. extending transversely and adapted to befastenedto the opposite in` ner links l of the two chains.

The two parallel' bars 13', 113 are in height and spaced apart adistance substantially equal to the diameter of the tubes, and in lengthequal to the distance `between the opposite links of the two chains. Theattachment of said bars 13', 13 to the links cl, may be accomplished invarious ways, Y

butl prefer to use the following construc-` Onthe innervextensions ofthepinsbof the two adjoining rollers a are mounted ver-` ticallydisposed recessed plates 16,. which.-v

`havelateral projections 16 yadaptedto vr'be passed. through holes madeiny the ends of `the bars `13" andtobe suitably fixed thereto inposition. vThe platesy 16 maybe steadied lin position on the pins b bycotter` pins-18 or the like. Each pair of bars 13, 13 form betweenthemselves al pocketl ldapted o t i f receive a tube 15; -The tubeslarehsomefI -what Ashorter than the pockets 14,' so, that i whenpositioned therein there is a free space formed at eachend Jforthe-accommodationof `a gripping member.. The two gripping members and.their arrangement 1n each pocket are identicahand I shall, therefore@describe the construction of the conveyor at the oppositeiside is tubesare open at their ends and are packed i with 'the'material'to betreatednotquite to f the ends, leaving free lspaces suiificientlyV largeto receive` they extreme ends of the' gripping bolts .19 whichwhen'movedginto operative position willfengage the tubes.; f

At points near the open'ends of the tubes."

\ vhen properly. positionedin the pockets 14, l provide `guide membersinform 0fapair of parallel plates 20'l arrangedin vertical positionv andprovided with central circular holes 20 in which the bolt-'19 is movablysupported. These guide members `2O are fixed in the bars 13 13 similarto the plates 16. The outer end of this locking bolt-19 is centrallyslottedin longitudinal direction as at 19. to movably engage ahorizontally 1- disposed bridge plate 271, which again "is fixedr to thebars13, 13 in like manner as plates 16.' This plate 21 isvr providedwitha longitudinal central recess 21" hav-ing at its inner end anenlargement 212. The bolt 19 is rectilinearly guided on ysaid l`plate-21by a guide pin 22 which passes ,through'the slot or recess .21. Borne inthe boltll9 is a. vertically movable lock pin 23` ofgwhich the upperpart24- is enlarged in diameter,

and which extends through the slot 21.

The, enlarged portion 2-1- of said 'spin projects outwardly or upwardlythroughl a correspondinglyenlarged bore 192 of the bolt.

rlhefree end of the reduced portion of the pin 23 is formed with` a headpiece 25, and agsprinn 26 is mounted around said reduced part of the pinto rest with one end against said headpiece and with its opposite endagainst the outer face of the bolt 19, the same having the tendency toIdraw the loclrl pin 23. downwardly. w"Ji/hen the bolt 19 isinlinoperativeposition the enlarged l, end 24; of the lock pin will bedisplacedrela- `tain guide pieces and cams rare providedr -for guidingthechains and the tubes and tive to the enlarged part 212 ofthe slot andthe` pin,v therefore, held in unlocked posi- -tion permitting the boltto be moved. l`When 4the, bolt 19 is moved inwardly or into locking'position, the part 2e ofthe locking pin comes into thejrange of thejopening 212 and snaps into it by force of' itsspring-26 and therebylocks the bolt in operative position. 5

"Extending from the` inner circumference .ofthe sprocket wheels 10 inthedirection of travelof the chains and below the latter is astationary bedlor base 17 `onwhich cerpairof guide memberk20'is a rail27. Theseymembers 20 are vsomewhat extended ver- `tically' totengjagethe sides ofsaid rail 27 whenthe conveyor *passesr over the table 17v so as toinsureA the proper positioning ber relative to the vcams lwhereby thelatter lare :adapted to be automatically operated.

There is acam 28 fixed' on the table 17 to extend in the path ofthelower end 25 of the locking pin for releasing said pin from its 'lockingposition.l This cam 28 is in form yof a bar extending longitudinally ofthe chains andhas an incline 28. Fiiied in the bolt 19 is a verticalpin'29 which projects downwardly towards the ta-ble'and rlockingpin 23and the consequent release of the enlarged part 24C thereof from theopening' 212 of the slot 21 this cam surface 30 vwill engage the pin 23and, as the conveyer proceeds in its travel,` cause the bolt 19 to moveoutwardly withdrawing its end from the tube 15, while the other camsurface 30 subsequently again engages the pin 29 and moves the boltpositively back into gripping position. There are also bars 32 iixed onthev bed 17 adapted to extend longitudinally thereof below the tubes ,15to sup-l port the same ywhile the conveyer passes over the bed. Thellatterat a place below the discharge end of the chutes is recessed as at17 to permit the tubes 15 afterv their unlocking to fallinto areceptacle (not shown) below the bed. p d

The mode of` `operation isjas follows:v

As the conveyer is 4delivered fromf the sprocket onto the`bed 17 thetubes Y15 pass onto the supports 32, the roller-sa ofthe chains', ontothe rails 26 and the guide bar 27 engages the guide member ,20. 'At theSametime the'lockingpins23 at both sides are engaged by the inclined 28"of the bars28 and are lifted releasing the upper ends24 of the latterfrom 'the' openings 212 ofthebridgevplates 21. As thejconveyer continuesto travel over the bed with the pins 23 unfloclred, the pins 29.`encounter the blocks 30 andk bythe cam surfaces ofthe-,latter are causedto move the bolts 19 laterally releasing them from the tubes `15, whichthus become unlocked one by one and fall through the recess 17 Vof thebed. l f

The emptied. pockets 14, as the conveyer proceeds are being `filled byfresh tubes 15 fed from the chute S and thesetubes on enteringthepockets are gripped by the bolts 19 automaticallythrough the, operationof the blocks 81, whose cam Vsurface 31 now engage the pins 29and/,positively move the bolts 19 into operative position. It is obviousthat the device may be variously modiiied without departing from theprinciple of my invention, an'dI', therefore. ,do'not wish to restrictmyself to the details "shownand described. l f y I s i t1 u n y o t eoperative par s o ne grippinginem- What l claim iszi 1.'In' a conveyer.yofv the character d'escribed, the coinbinationfwith tubular coiitainersopen at their ends, of laterally movable members adaptedto enter theopenends of said containersto retain them in position.
